    摘要: An electric power steering apparatus is provided that has a controller by which no current flows in one phase among current paths of three phases for supplying electric power from a motor driving circuit to a three-phase brushless motor and currents that have an identical absolute value and that have different signs flow in the other two phases. Thus, the status at one energization angle on the driving current waveform of the three-phase brushless motor can be given continuously and relatively-high currents can simultaneously flow in opposite directions in the contacts inserted to the two phases. By flowing of such high current in the contacts, a secure conduction check can be performed and foreign matters on the surface of the contact can be fused or thermally destroyed.

    摘要: A method for producing film-coated alkaline-earth metal silicate phosphor particles that can have improved light-emitting characteristics may include a coating film having high moisture resistance. Strontium-containing alkaline-earth metal silicate phosphor particles are pretreated with an alkaline-earth metal compound solution whose strontium compound concentration is 1 to 15% by mass with respect to the phosphor particles and whose pH is 6 or higher but 10 or lower. Then, a base layer of an aluminum organic metal compound is formed on the surface of the pretreated phosphor particles. Then, the phosphor particles are coated with a coating material composed of a partially-hydrolyzed condensate of a silane organic metal compound, and are then dried and heat-treated to form, on their surface, a coating film made of an amorphous inorganic compound mainly containing Si and O.
